Bun-BOTTOM;

nan-.299.

To all-whom it may concern Be'it known that'I, BEN AMIN H. JONES, a citizen of the United States, residing at St; Louis, State of Missouri, have invented certain new and useful Improvements in Bed-Bottoms, of which the following is a full, clear, and exact description, reference being'had to the accompanying drawings, forming a part hereof. e

The present invention is directed to iniprovements in bedbottoms, and particularly tothe frame to which the usual link fabric composing the-spring mattress is secured;- The object sought is to provide a corner bracket to which the side and end rails of the frame maybe quickly and con vicntly secured, provision being made to secure the ends of the sidebars or members of the fabric directly to the adjacent ends of the end rails ofthe frame. A further object is'to provide a frame the parts of which may be quickly assembled; one which will not sufier, distortionunde'r theload imposed on the fabricor mattress, one Which is simple, and one possessing further andother advantages better apparent from the following detailed description in connnection with the accompanying drawings in WlllCll-- he Figure 1 represents a plan of a bed bot tom showing onelform of my invention applied thereto; Fig; 2 is an end view of" the frame, the rail being broken away in partsg.

Fig. 3 is an outer side elevation of the corner bracket showing the terminal of the side rail engaging the socket thereof; Fig. 4 1s a perspectiveof one e'ndofthe end rail; Fig.

- 5'is a perspective of the corner bracket supporting the d andside rails, Fig. 6 is'a c1oss sectional detail of the bracket on the line 6 -6 of Fig. 2 ;"Fig. 7 is an inner side elevation of the corner bracket showing the offset in the wall which supports the end rail; Fig. 8 is an inside face elevationof the corner bracket or looking toward the left on Fig. .7 Fig. 9 is an elevation of the side rail broken in themiddle;Fig. 10 is a crosssection on the line 10-10' of Fig. 9; Fig. 11 is an end View of the rail; and Fig. 12 is a top plan of a modified form of corner bracket.

Referring to the drawings, and for the present to Figs. 1 to 11 inclusive, 1, 1, represent the end rails, 2, 2, the side rails, and

3' the link fabric coupled to the end rails as well understood in the art. The meeting ends of the several rails are usually secured to suitable corner bracket-s, the construction of which is materially improved by my invention. In the main form of the present embodiment of. the invention the corner bracket comprises an inwardly convexed arm or riser 4: terminating at the base in a substantially elliptical socket 5 for receiving the elliptical (or other form of non-circular) end 2 of the side rail 2, said rise'r'a forming the inner member or arm of the corner bracket, and being connected. at the bottom with a similarly inwardly COlIVGXBd rls'er- 4" forming the outer member; or arm,

the bottom connection being effected through the cross member 4: leading from the base of the socket 5. The upper end'of the riser" 4E'leadsf1o1n th rail-supporting wall 6 of the corner-bracket, the Outer face of said wan 6 being offset inwardly from the outer face of the rounded corner 7 of the bracket, and

being likewise depressed below the top edge of said roundedcorner for a pur'posepresently to appear; The offset referred to is represented" by the reference letter n and the depth of thedepression of the upper edge of the wall 6 below the upper edge of the corner 7 is represented by thev shoulder t. Formed along the inner faces of the'wall 6 and corner wall 7 is a bead or'ledge 8 to increase the surface of support for the end rail 1 carried by the corner bracket.v The end rails l are of the usual angle-bar construction, except that in the present embodiment of my invention the horizontal leg of the baris formed with a terminal lobe or tongue extension at conformable to the rounded corner or wall 7 the said horizontal leg beingdeposited onthe upper edge of the corner-bracket Wall 6, the verticalinner face of the bracket wall as previously described. I The wall is provided with openings 0 for receivingthe screw bolts 6 by which the end rail is secured to the cori ner bracket. The formation of the lobe or tongue it results in a shoulder or offset a, the

offsets n, a, coming together when the parts,

are assembled so that the .end rails 1 are practically shouldered to the corner bracketsand held against longitudinal displace ment across the bed frame. The lobes a of the end rails completely fill the corners of the brackets (Fig. 1), said lobes being availed. of'to anchor thesprings -10 to which the side bars 11 of the link fabric are secured. It willbe seen (Figs. 1, 3, 5,) that the arms 4t, 4t, are oonvexed or arched i11- wardly or toward the transverse aXis of the bed bottom, this inward arching taking up to bette'r advantage the strainsto which the 7 frame is subjected under the load carried by the fabric 3.

As well understood in the art, the side rails 2 when first installed in the frame are slightly cambered, the strain imposed thereon in service causing the same to straighten out. .Toprevent axial turning of these rails under the straightening action is the object of the elliptical or ovalterminals 2 and the ways rest evenly in the Well of the bed. I

am 'awarethat the use of tubularside rails elliptical or non-circular in cross-section is old, but I am not aware of cylindrical rails terminating in elliptical ornon-circular formations as here shown and described. A cylindrical pipe (that is, circular in crosssection) 1s cheaper to construct and maybe always kept in stock; and when the occas sion comes to construct a rail therefromthe ends thereof may be squeezed out of round with the same ultimate results as with the 1 use of pipes or tubes that are non-circular in cross-section. I

. I need not of course llmlt myself to a corner bracket having arounded corner. Thus,

a' corner bracket 20 with a square corner 21, the rail 1 being formed with a square lobe a. in lieu of the rounded lobe a in the first form described. 'I mayfdepart from the present constructionin minor particulars V ,for the rail supported thereby. in the modification shown in Fig. 12, Ishowv claim is Y 1. In. a bed-bottom frame,a cornerbracket provided with ariser or arm terminating at "the top in a rail-supporting wall offset in- .wardly from the outer bounding face of the corner'wall of the bracket'and 'depressed below the upper edge in which said corner wall terminates, the: corner ofthe bracket being formed to receive the adjacent terminal of.

the rail supported by the-wall aforesaid, weirtending beyond theofiset against which the,

main body of the rail is shouldered. Q

2.111 combination with a corner bracket of a bed bottom frame provided wlth a riser I terminating at the top in a rail-supporting wall offset inwardly from the outer face of the corner wall of the bracketand depressed below the upper edge of said corner wall, an" angle rail having its horizontal leg terminating in a lobe conformabletothe contour of the corner wall, said-leg resting on the rail-supporting wall of the bracket, the edge of the lobe being offset from the outer face of the vertical leg a distance equalto the depth of they ofi'setjof therailssupporting.

wall from the corner of thebracket, and the thickness of the horizontal leg. conforming substantially to. the depth of the shoulder between the upper-edge of the corner and. the depressed, edge of the'r'ail-supporting wall, said lobeservingias a means for'anchoring the side meinbers ofithe link fabric of the bed bottom thereto. p T

3. A bed-bottomcorner bracketcomprising a pair of arms connected at -the bottom and spaced apart, a wall connecting the upper ends of the arms, a portion of said wall operating'as a railsupport and being 7 offset inwardly from the outer face of the corner portion ofthe wall, and having its upperedge depressed below the corresponding edge of the cornerportion, a socket at the base of the inner arm for receiying the adjacent end of a side rail, the aforesaid wall of the bracket being provided with a ledge to afford anlincreased'bearing surface In testimony whereof l afii 2: my signature Witnesses: L
